  • How to distinguish between heavy failure and light failure? In the event of a minor fault, the system will issue an alarm signal and the fault indicator will flash.
  • What are the minor faults? Minor faults include: transformer overheating alarm, cabinet overheating alarm, cabinet door opening, unit bypass. The system does not store records of minor faults, only displays the fault indication.
  • What are the heavy faults? When the following faults occur in the system, they are treated as major faults and the type of major fault will be displayed in the upper left corner of the monitor.
  • The transformer over-temperature alarm is triggered when the temperature measured by the transformer thermostat exceeds its set alarm temperature (which is set to 100℃ by default).
  • When the temperature of the temperature measurement point of the over-temperature alarm unit cabinet is greater than 55 ℃, the system will send the failure alarm.
  • When transformer overheating, transformer temperature measurement temperature is greater than its set trip temperature (default setting is 130 ℃), the temperature controller trip contact closed, the system will report the transformer overheating heavy failure.
  • The cabinet temperature is too hot. When the temperature of the unit cabinet’s measurement point exceeds 60°C, the system will report a severe cabinet temperature overheating failure.
  • The cabinet door interlocking alarm travel switch is compacted with the top of the cabinet door. Check if the ‘pre-travel’ and ‘over-travel’ settings of the travel switch are appropriate and if the electrical function of the travel switch is functioning correctly.
  • The controller does not communicate. Ensure that the communication cable connecting the monitor control board to the main control board is properly connected, and verify that the +15V and +5V readings on the monitor control board are accurate.
  • Main control board failure. The monitor detects a fault in the main control board and reports it as such if it has established communication with the controller.
